I used a 250cc engine for buid, the engine has four forward gears and a reverse gear, the wheels are derived from the quad bike, the front is from the motorcycle. I bought all the parts used from auction sites.
I have no experience in building such vehicles, so the work on this trike motorcycle took some time, but the end result is satisfactory, riding this motorized trike is great fun :)

COMMENTS: - -You Sir, are an excellent fabricator!!! Your gussets are exactly where they need to be! Your material thicknesses are 100% right on!!! Great job!!!
I have spent my entire working life in factories...of all types! From Cushman Motor Scooters to automobile Trucks, and finished my career in Aviation with twin jet aircraft!!! I know something about great mechanical fabrication, and you my friend, could work anywhere, and do top notch work!!! Thanks for letting me see your talents!!!

It's so satisfying to watch this building these super cool creations , a real high skilled and top notch pro ! With some big wide a$$ wheel guards in back i think it'd get even more sick . I loved it

Really great build, always look forward to what you come up with next. A couple of things... where did you learn fitment, welding and heck even the plans for some of these builds... at your job?  Next I am surprised you haven't built rotary welding positioner.

Really amazing!  I am so impressed with the things you are able to build.  I think I would want a back rest on that seat so I didn't slip off!
